Hello, I'm trying to make a mod that creates an additional world type. This additional world type is exactly the same as "Customized", except that all of the terrain generation variables are set to random values automatically so you jump into a very odd and entirely unexpected world each time. I've already found the ChunkGeneratorSettings class and the WorldType class, and I've got the basic outline of the mod started (Forge recognizes my mod exists but it does nothing yet, gotten via tutorial). I'm in an AP Computer Science class right now - third quarter - so I'm able to understand what most of the code is doing here. But this is a whole lot to take in at once and I don't know how to approach doing this or how to modify/override things inside a referenced library. Any help and suggestions is appreciated. Thanks!
